DVD43 is a free DVD decrypter that runs in the background and decrypts DVDs on the fly. DVD43 will decrypt (unlock) a movie DVD so that your copy program can read it. If the DVD structure is non standard or the DVD contains bad sectors, your copy program needs to take care of that. Outdated copy software like DVDXCopy can't handle bad sectors commonly found on newer DVDs. You need a copy program that provides frequent updates to handle new movies as they are released.
